If you're running from RPMs (maybe from yum.postgresql.org), you can install
postgresql10-debuginfo (maybe using: "debuginfo-install postgresql10").

Just be sure it installs the debuginfo for exactly the same RPM (rather than
installing a new minor version, for example).

If you compiled it yourself, you can probably point GDB to the un-stripped
binaries.  Again, assuming you have binaries from exactly the same source
version, no additional patches, etc.
